Driving your vehicle in summer is never wrong if you are comfortable with an AC in it. However, the common problem is that the car overheats when AC is on. It is good to know the actual reasons when this happens because you will find the right solution for it.
When your car overheats after turning on the AC, it means that there is a problem with the pump, the compressor, or the condenser. It is better not to use the AC until it gets fixed whenever you see such symptoms.
Reasons why the vehicle overheats when the AC is on
If you ever notice that the dashboard and the seats of your car begin to overheat when the air conditioner is turned on, then there is an issue with your vehicle. Keep in mind that it happens with many cars and this issue is quite common in the world. The following are why the car overheats when the AC is on.
One of the main reasons your vehicle overheats when the AC is on is the compressor overload. The compressor has to work with the engine when the engine is turned on. The compressor then moves the refrigerant cylinders to compress, thus creating pressure on the machine. As much power is drawn by air conditioning from the engine, it can eventually overheat.
A bad cooling system
The cooling system plays a very crucial role in a car AC system. The job of the cooling system is to keep the condenser cool. The air conditioner heats up by turning on, whereas the cooling system cools it down and gives cold air. Therefore, if you have a clogged cooling system, there are chances that the condenser temperature will rise, which can overheat the car.
Problem with the radiator
The radiator's job is to pass the coolant into the engine, which plays a significant role in your vehicle. The car can operate properly when it passes the coolant through the metallic fins. So, when there is a problem with a radiator, then there are chances that the vehicle overheats when the AC is on.
A faulty fan
The engine fan also has a significant role because the car can overheat if you have a faulty fan. This problem can happen because of a lack of airflow through the condenser and the radiator. If your lover has a blockage in the fins, it is broken, or it blocks the radiator and the condenser, then there is quite a possibility that it may cause the car to overheat when AC is on.
A defective coolant sensor
You may face a problem with the engine coolant temperature sensor, and when this happens when you turn on the AC, your car can get overheated. When the temperature starts rising, and the sensor reads it usually, then there is a possibility that the engine could overheat. Therefore, the functioning of the thermostat should always be checked.
It is essential to include your car's cooling system when periodic checks. It is better to hire an expert to do the job. If you have a problem with car overheating when AC is on, you should call a professional, especially when you are unsure what to do. Your car engine can have severe problems because of abnormal heating, which can even lead to internal damage. Therefore, you need to be observant and take the proper steps when required.
